' 'miroir-SIGNAL."

To @ZZ 'Lc/om t may concer/n.'

Be it known that I, ALEXANDER LAwmeNoE CURRiE, a subject of the King of Great Britain, and resident of the village or Sorel, in the `Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in T rack-Signals, of which the following` is a specification. y

This invention. relates to improvements in track signals of the type adapted to be removably adjustable relatively to the track b v working gangs or other' parties who are temporarily 'using the -tracksorrfor yard purposes, or under any circumstances in which manual flagging is at present em-4 ployed, and the objects of the invention are y to improve andsimplify'the construction Vof the signalv and to adapt the various parts to better perform the functions required of them.

With the above and other objects in view, the invention consists essentially of the improved construction hereinafter described in detail in the accompanyiny specification' and drawings.

In the drawings: Figure 1 is a front elevation of an embodiment of my invention.

Fig. 2 is a fragmentary enlarged elevation of the base member and Hag supporting arm. Fig. 3 is a plan view of the rod engaging and supporting the flag.

Fig. 4 is a fragmentary front elevation ofthe clamping member for engaging the fiange of the rail.

Fig. 5 is a fragmentary front elevation of an alternative cam clamping means whereby the base member is secured to the lower ange of the rail. y

Fig. 6 is a fragmentary front elevation of an alternative form of cam clamping member for securing the base to the flange of rail.

Fig. 7 is a fragmentary front elevation of another alternative means for securing the signal to the ball of the rail.

Like characters of reference refer to the like parts in the several figures.

In the drawings, A representsra rail of a track and B the improved signal attached thereto. Y

This signal comprises a base member 10 having a flattened end 11 formed with a hook gripping member 12, and the flattened portion of the base 10 is designed to underlie the rail A, so that the hook gripping i Specification of Letters Patent.

member will engagewith the lower :li-ange of the "said rail." i p i The opposite .end lof the vbase member 10 is offset and tubular and provided with a Z-shaped slot' la.' The base member 10fis secured in positionv by meansof a clamping` l plate 15, anda ring 16 embraces the plate lo and flattened portion 11 of the base 10,

so that the plate 15 may be tightened intoV engagementwith one of the lower flanges of the rail by means of a set screw 17.

The ends'of the plate 15 are offset in opposite directions, "one end to engage with the fiange ofthe rail A, and the other end' to hold the plate l5 in spaced relation from the fiattened portion 11 of the base 10, so that as the set screw' 7 is tightenedit will force the )')l'ate 15 against the flange of'the rail to hold the basememher 10 in position.

The rod 18 has a pin 19, on its lower end which slidably engages with the Z-shaped slot 14;, so that as the rod 18 is pushed into the offset tubular end 13 of the base member 10, the pin will slide down the slot until it reaches the bottom thereof, but it should be particularly noticed that the rod 18 is'given a slight turn, when the pin 19 reaches the center of the slot, so that the said pin may be brought into alinement with the lower arm ofthe Z-shaped slot. It will be evident that the rod 19 cannot become disengaged from the tubular end 13 of the base member 10 unless the said rod is' manually and intentionally removed. v

The upper end 2O of the rod 18 is flattened forming a shouldergand an elongated eyelet 21 formed on one end of the rod 22 engages with the flattened end 20 of the rody This rod 22 carries the iag 23 hung therei from, which is prevented from becoming disengaged by the offset end on the rod, and flag may be weighted so that it will hang in proper position but will not ,prevent the flag vfrom fluttering, and the flag may be rendered visible at night time by hanging a lamp from the upper end 20 of the rod 18.

This type of a signal can be 'very easily set up and secured in position and will not work loose through `iarring or from any other cause.

The clampingmember shown in Fig. 4, is an alternative to that shown in Fig. 1, in that, the set screw 17 is threaded through the outer end of the plate 15, and the ring 16 is used in this type, and, as the set screw grip whichy may lbe actuated to force the plate against the flattened portion 11 of the base member 10'and against thelower flange of the rail A. v i

Fig. 6 differs from F ig.V 5 with respect to the location of the cam 25a which is positioned in the end ofl the plate 15a. When the cam 25il is used, the plate ll has its outer offset rend removed but the inner offset end coacts'with the lower flange of the rail A, and the ring 16 is used so that on actuation of the cam 25a the plate 15a will be forced hard against the lower flange of the rail A to secure the signal in positlon.

In Fig. 7 the rod is provided with a laterally'` turned lower end 2 adapted to extend across the top of theV rail and formed with a downwardly turned projection 3 adapted to engage the side of thehead of the rail A.

4 represents a projection depending from the offset end 2 of the rod 1 and extending to the opposite side of the rail head to the end 2, and adapted to receive a screw threaded crank 5, the end of which is adapted to bind against the side of' the rail A.

As many changes could be made in the above construction and many widely different `embodiments of' my invention within the scope of the claim, constructed without departing from'the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claimV as my invention is: y

A track signal, comprising a-base member having a clamping means for securing same to a rail and provided with an offset end, a flag carrying member engaging with the Voffset end and provided with an upper offset end, a rod having an eyelet vengaging with the offset end of the llast said rod, a flag mounted inthe second rod and means for weighting the lowerV end of' the flag to hold it in position but not impair its fluttering.

In witness whereof I have hereunto set my hand. l n ALEXANDER LAWRENCE CURRIE.
